With the above and such other objects lde plates l0 can be secured tothe arm,

From the foregoing it Will that the transparent plates 4 are adapted toprotect the body 2 from the forces of nature, the plates 4 eing made ofglass or other transparent material having a flat smooth surface beingreadily cleaned and maintained in such condition that the colors carriedby the inner faces of the plates 4 or be observed in the scope of theappended claim the outer faces of the body 2 can be readily In tiedraWing:-Figure l is an elevaobserved by an engineer or motorman.
